Round-the-world echoes are certainly possible under conditions like we have 
had on 10 in recent weeks.  I heard some of that on some of the European 
stations with really high antennas last weekend.  Last Tuesday, when the 
federal government was closed for snow, I heard WX3B running Europeans on 10 
meter phone.  For fun I turned my beam southwest (the opposite direction, to 
get the best long-path signal) and worked him.  We had nice round-the-world 
echoes on our signals.
One time, listening during a big DX contest on 10 in the previous sunspot 
cycle, I heard a double RTW echo on W3LPL's SSB signal.

But the typical back-scatter situation is that we point our beams south, 
southwest or west, while stations further west may also point their beams 
south or southeast, so we can work these folks via a reflection off the Gulf 
of Mexico.  Here on the East Coast, before 10 or 15 opens to Europe on a 
direct path, we can work major European stations who are beaming toward 
South America; the skew-path reflection is from a large area of the Atlantic 
Ocean that is visible to both ops.  But I think you know all this, anyway. 
I just enjoy studying propagation.

I am not sure that it was back scatter, rather multi path propagation.

A G yesterday at about 0800 reported hearing a VK station with multiple
echoes indicating travelling around the world.

Hard to tell if it was back scatter, or e-skip.  For some reason, their is
e-skip in December, as well as May June, and July.  I have never known why.
